Hair loss may be a common issue, but that doesn't make it any less frustrating to deal with. There can be a wide range of reasons why you're experiencing thinning, like genetics, diet, pregnancy, age, and stress—but luckily, there are measures you can take to reduce hair loss and help your hair grow back thicker and stronger. The best hair growth products don't have to set you back a ton financially, either: For Amazon Prime Day 2021, many of the site's top-rated and best-selling hair growth treatments are on sale.

The Best Hair Growth Products on Sale for Amazon Prime Day 2021:

The best hair growth products contain ingredients that both inhibit hair loss and encourage healthy growth. One popular option is the FDA-approved topical minoxidil (aka Rogaine), which is clinically proven to help regrow hair, dermatologist Christine Shaver of Bernstein Medical Center for Hair Restoration in New York City previously explained to Health. Ingredients that block buildup of DHT, a hormone that contributes to hair loss, are helpful, too, and clarifying shampoos that aim to remove dandruff and product residue from the scalp can also play a role in encouraging hair growth. There's no one miracle product—but there are plenty of options that can make a big difference.

With impressive ratings and customer testimonials, the below products are some of the best solutions to hair loss, according to Amazon shoppers. And thanks to Amazon Prime Day, they're all marked down well below their regular prices. To take advantage of these deals, you'll need to have an Amazon Prime account, which will give you free two-day shipping on qualifying orders, too. If you're not yet a member, you can sign up for a 30-day free trial here—and immediately proceed to shop these hair growth products that are exclusively on sale for Prime members (along with teeth whitening products, comfortable sneakers, and more).
